Answer:

x=$200

Step-by-step explanation:

cross-multiply

130=0.65x

Answer:

x = - 1  

option I

Step-by-step explanation:

Equation is: 5x + 6 = 1

Subtract 6 from both sides

5x + 6 - 6 = 1 -6

        5x = -5

Divide both sides by 5

5x / 5 = -5/5

x = -1

Answer:

4

Step-by-step explanation:

Since we have 2 points, we can find the slope using

m = ( y2-y1)/(x2-x1)

    = ( 7-3)/(9-8)

    = 4/1

   = 4

(8, 3) and (9, 7)

The slope of the line passing through the points (8, 3) and (9, 7).

y2 - y1 / x2 - x1

7 - 3 / 9 - 8

= 4 / 1

= 4

Answer:

50mph

Step-by-step explanation:

to to find the mean you add 40 + 60. which equals 100 then divide by the amount a variables which is two.

Answer:

consider integer are x, x+1, x+2, x+3

now x+(x+1) + (x+2) + (x+3) = 34

or, 4x + 6 = 34

or, 4x =28

x= 7

x =7

x+1 = 7+1 =8

x+2= 7+2=9

x+3= 7+3 =10

Answer:

7/41

Step-by-step explanation:

There is a 34/41 probability that this event will happen so to find the probability of which the event will not happen, the subtract 34 from 41 to get your answer.

41-34=7

Therefore, 7/41 is the answer.

Ps. is the P(E) included in the main question? if it is, the the answer might differ from the one I am giving you.

Step-by-step explanation:

t = 9x, and dx = 1/9 dt.

∫ sin(9x) dx

= ∫ sin(t) (1/9 dt)

= 1/9 ∫ sin(t) dt

= -1/9 cos(t)

= -1/9 cos(9x)

[tex]g=20[/tex]

Step-by-step explanation:

[tex]4\left(g-17\right)=12[/tex]

Divide both sides by 4:

[tex]\frac{4\left(g-17\right)}{4}=\frac{12}{4}[/tex]

[tex]g-17=3[/tex]

Add 17 to both sides:

[tex]g-17+17=3+17[/tex]

[tex]g=20[/tex]

Answer: g=0 or g=20 i hope this helped

Answer:

1 inch= 4 feet for both

Step-by-step explanation:

This also means that the scale converts to 1/4 in. = 12 in.

stay safe

Using proportions, it is found that the scale is of 0.25 inches per feet.

The rule of three is:

3 inches - 12 feet

x inches - 1 feet

Applying cross multiplication:

[tex]12x = 3[/tex]

[tex]x = \frac{3}{12}[/tex]

[tex]x = \frac{1}{4}[/tex]

[tex]x = 0.25[/tex]

The scale is of 0.25 inches per feet.

Answer:

Combined age = 5x+4 years

Step-by-step explanation:

let Eliza's age be x

given that Andrea is three times older than Eliza, hence Andrea's age is

= 3x years

it is also given that Suzie is 4 years older than eliza, hence Suzie's age is

= (x + 4) years

Therefore the combined age

= Eliza's age + Andrea's age + Suzie's age

= x   +   3x     +     (x+4)

= x + 3x + x + 4

= 5x + 4

Answer:

35:60 times

Step-by-step explanation:

The proportion of time in which the coin land on Heads is 0.58

A proportion is an equation in which two ratios are set equal to each other.

Now it is given that,

Number of times coins tossed = 60

Number of times coin landed on Heads = 35

Therefore, the proportion of time in which the coin land on Heads is given as,

Proportion of time the coin land on Heads = Number of times coin landed on Heads/Number of times coins tossed

⇒ Proportion of time the coin land on Heads = 35/60

⇒ Proportion of time the coin land on Heads = 7/12 = 0.58

Thus, the proportion of time in which the coin land on Heads is 0.58

Answer:

Step-by-step explanation:

Look at tenth place. If it is 5 , 6 ,7 , 8, 9 ( 5 or more than 5)then add 1 to the whole part and that is your answer

If it is 0,1,2,3,4, then write the whole number as it it.

a) 8.71

tenth place is 7 and it is more than 5. so, add 1 to the whole part. 8+1 = 9

8.71 = 9

b) 26.01

Tenth place is 0 and it is less than 5.So, write the whole number as it is.

26.01 = 26

c) 69.48 = 69      { 4 is less than 5}

d) 103.72 = 104   { 7 >= 5}

e) 49.84 = 50  { 8 >= 5}

f)101.35 = 101  

g) 39.814 = 40

h)1.23 = 1
